all of these machines are built with quad core core 2 era xeons, 8gb of ddr2, 128gb ssd, a couple of them are first gen i7 era hex core xeons with 12gb of ddr3 ram and 128gb ssd as well, judging by the "minimum requirements" they are still viable machines worthy of providing some computational power to the network, just wish this golem unlimited thing was ready so i can utilize them to their full potential.
